Abstract
A refrigerant evaporator 5 constructed by a refrigerant-refrigerant heat exchanger section 32 having an inflow passageway 38 and an outflow passageway 39, and a refrigerant-air heat exchanger section 34 having a bottom tank 48, a top tank 49 and evaporating passageways 100 connecting the tanks 48 and 49 with each other. An orifice 33 is arranged between the inflow passageway 38 of the refrigerant-air heat exchanger section 34 and the inlet tank 48 of the refrigerant-air heat exchanger section 34. The refrigerant in the bottom tank 48 is introduced into all of the evaporating passageways 100, so as to obtain a single, upward direction of flow of the refrigerant in the evaporating passageways 100.
